Atropelamento da fauna silvestre e sua relação com a paisagem em um trecho da rodovia PR-281 no sudoeste do estado do Paraná

Abstract

Mortality from vehicle collisions is the most visible impact of road traffic on wildlife. This roadside mortality can affect not only the environmental quality but the population dynamics of various species and can therefore increase the local risk of population decline or extinction. This is especially true in Brazil, where plans for the development of road networks end up overlapping areas considered to be biodiversity hotspots, which configure areas of great importance for the conservation of this diversity. In this sense, this study aimed to survey the wildlife roadkill and evaluate the effect of the road landscape on animal collisions on a state road in the southwest region of the state of Paraná, between the cities of Realeza, Planalto and Capanema. For this, the animals were photographed and identified, as well as characterized the landscape around the highway, to later analyze and compare the data obtained, separating by class, calculating the mean per kilometer in order to understand the dynamics of this impact on the local fauna community. By visualizing the carcasses, it was possible to record 164 animals belonging to four groups Amphibia, Mammalia, Birds and Squamata (order), divided into 38 species. Regarding the relation of collisions with the landscape, a greater incidence is observed in agroforestry areas, forest fragments and the association of these areas.
